Deal with the market leader in protective coatings and remedial services in Australia


Waterproofing, making a surface or a building or structure waterproof or water-resistant, is done with the use of membranes and coatings to protect contents underneath or within as well as protecting structural integrity. A structure will need waterproofing in order to extend its life and protect the contents within the structure.

Nothing can cause damage quite like water leaking into a structure. Moisture intruding into a building’s structure can create a variety of problems, such as mold and bacteria. In addition, moisture can add to the deterioration of wooden support structures. To prevent moisture from seeping into buildings a proper waterproofing method is essential in keeping offending water out.

In recent decades, the construction industry has had technological advances in waterproofing materials which has provided the industry with more advanced membrane materials. New technology in waterproof membranes relies on polymer-based materials that are extremely adhesive to create a seamless barrier around the outside of a structure.

Depending on your requirements AWS will make a recommendation on what system you require and which membrane should be used for your project, our recommendations come from experience and long, tried and proven practice


AWS is a market leader in spray applied protective coatings and membranes. Protective coatings will extend the life of your Assets and increase the durability of the structures.

With the cost reduction in manufacturing of the polyurea product, we are now able to use this product on all types of projects, once only available to the mining and water treatment industries.

Depending on your project, there is a spray applied coating to suit your need from car parks applications to water treatment areas. This product is the best coating in the world, able to be driven on the durability of this product is second to none with a limited down time capacity most of our spray applied coatings have a drying time of one minute.

Depending on what capacity polyurea has the ability to add strengthening and sound proofing properties to your structure.

These coating come with our AWS 10-year warranty.

Polyurethane Membrane

AWS Supply and apply polyurethane waterproofing membrane using a 3 coat system, fast drying and seamless.

The polyurethane membrane is ideal for applications that require sealing of the surfaces, such as the interior walls of water tanks.


AWS supply and install the best waterproofing membranes for the situation at hand, each situation is different in regards to what membrane we use or recommend you use on your project. AWS carries a large variety of membranes as we believe that no membrane can be used in every situation.

AWS has a large range of Acryllic membranes available to suit many different applications and environments. Joints are caulked and bonding tape used on all expansion joints to ensure the membrane performs to its desired effect. Membrane failures occur most commonly when the application is not given the proper attention needed to ensure no leaking happens.

At AWS all technicians are trained to identify problem areas and to apply the proper procedure to each situation to ensure the job is done right the first time. AWS has its own spot check system in place so we can assure the best outcome for all our projects and peace of mind to the end user of the structure.


Bentonite waterproofing combines the active waterproofing benefits of sodium bentonite with the strength and durability of a thick geomembrane liner.

Unlike other membrane systems that require precise installation, a reactive bentonite compound can expand to seal small punctures in the membrane.  Bentonite works by forming a continuous membrane upon hydration with water. When confined under pressure, the swell is controlled, forming a dense, positive seal against the concrete


AWS Supply and apply all types of torch applied and sheet membranes, we install mineral or straight 1 layer torch applied.

With torch applied membranes, the most common failures is the detailing of penetrations and the overlapping of edges, at AWS we ensure the area is primed and each detail is looked at prior to applying the membrane, Torch applied is a heavy duty form of waterproofing, typical in retaining applications and blinder applications as it is a thick bitumen that enables heavy traffic & UV rays don’t damage the membrane.

AWS also specialise in PVC, heat welded sheet membranes typical in internal commercial plant rooms and mechanical applications.


Self-adhering sheet waterproofing membranes provide a simple peel-and-stick application. These membranes are ideal for use in the tunnel sector, industrial plants, shopping centre roof tops and below-grade work in commercial construction.

Application Advantages:

Self-adhered membranes offer several initial advantages. First and foremost, they appear to address the current safety and environmental issues. The application of these sheets is completed with no heat and no fumes, which makes them relatively safe to apply. They are also environmentally friendly because there are no volatile organic compounds in the material.


PVC is one of the most durable waterproofing options. It is a product that has proven it can serve its purpose for a longer period of time without need for replacement.

PVC membranes offer many other benefits including:

  • Good low-temperature flexibility and high-temperature tolerance
  • Inherently fire resistant
  • Highly puncture and impact resistant
  • Easy to repair
  • Available in a spectrum of colors including energy efficient reflective white
  • Proven durability against rooftop soiling and contamination
  • Installation friendly and installed by a variety of attachment methods
  • Aesthetically appealing, and can be used to create the look of standing seam metal
  • Provides excellent visual feedback of workmanship during and after installation
